“…In grape, a similar rise in VvNCED1 and ABA accumulation at ripening initiation has been documented (Coombe and Hale, 1973;Deluc et al, 2009;Owen et al, 2009, Wheeler et al, 2009. ABA is now considered to be a key regulator of ripening in grape and other nonclimacteric fruit.…”

Highbush blueberry (Vaccinium corymbosum) fruits contain substantial quantities of flavonoids, which are implicated in a wide range of health benefits. Although the flavonoid constituents of ripe blueberries are known, the molecular genetics underlying their biosynthesis, localization, and changes that occur during development have not been investigated. Two expressed sequence tag libraries from ripening blueberry fruit were constructed as a resource for gene identification and quantitative realtime reverse transcription-polymerase chain reaction primer design. Gene expression profiling by quantitative real-time reverse transcription-polymerase chain reaction showed that flavonoid biosynthetic transcript abundance followed a tightly regulated biphasic pattern, and transcript profiles were consistent with the abundance of the three major classes of flavonoids. Proanthocyanidins (PAs) and corresponding biosynthetic transcripts encoding anthocyanidin reductase and leucoanthocyanidin reductase were most concentrated in young fruit and localized predominantly to the inner fruit tissue containing the seeds and placentae. Mean PA polymer length was seven to 8.5 subunits, linked predominantly via B-type linkages, and was relatively constant throughout development. Flavonol accumulation and localization patterns were similar to those of the PAs, and the B-ring hydroxylation pattern of both was correlated with flavonoid-3#-hydroxylase transcript abundance. By contrast, anthocyanins accumulated late in maturation, which coincided with a peak in flavonoid-3-O-glycosyltransferase and flavonoid-3#5#-hydroxylase transcripts. Transcripts of VcMYBPA1, which likely encodes an R2R3-MYB transcriptional regulator of PA synthesis, were prominent in both phases of development. Furthermore, the initiation of ripening was accompanied by a substantial rise in abscisic acid, a growth regulator that may be an important component of the ripening process and contribute to the regulation of blueberry flavonoid biosynthesis.Highbush blueberry (Vaccinium corymbosum; Ericaceae) is one of the most economically important fruit crops in North America. Blueberry fruit have been the focus of much recent attention due to numerous reports of their positive effects on human health. These benefits are generally attributed to high levels of polyphenolics, in particular the flavonoids (Rasmussen et al., 2005). Highbush blueberries have one of the highest in vitro antioxidant capacities of any fruit or vegetable (Prior and Gu, 2005;Wu et al., 2006). The major health benefits linked to the consumption of blueberries include a reduced risk for cardiovascular (Basu et al., 2010) and neurodegenerative (Neto, 2007) diseases. Furthermore, experiments on rodents suggest that blueberry extracts may also prevent cancer, slow tumor growth, and reverse cognitive and behavioral deficits related to stroke and aging (Lau et al., 2005;Gordillo et al., 2009).The three common types of flavonoids that accumulate in blueberry fruit are the flavonols, anthocya-

“…Exogenous ABA was found to stimulate lipoxygenase activity, promote JA production, activate peroxide oxidation of membrane lipids, contribute to the formation of tolerance when rice leaves are wounded [96]. A positive correlation between the ABA concentration and LOX transcript content was revealed in water-stressed plants [97]. Mechanical wounds lead to an increase of LOX activity, ABA and JA content [98,99].…”

“…In berries, the onset of ripening (veraison) when anthocyanin accumulation begins in red varieties, is accompanied by a marked increase in ABA concentration (Deluc et al, 2009;Gambetta et al, 2010) and correlates well with sugar accumulation (Gambetta et al, 2010). ABA has been shown to activate anthocyanin biosynthetic genes and the anthocyanin-synthesis related VvmybA1 transcription factor (Jeong et al, 2004), and to induce the delay of expression of proanthocyanidin biosynthetic genes (VvANR and VvLAR2) (Lacampagne et al, 2009).…”

Plants can maintain growth and reproductive success by sensing changes in the environment and reacting through mechanisms at molecular, cellular, physiological, and developmental levels. Each stress condition prompts a unique response although some overlap between the reactions to abiotic stress (drought, heat, cold, salt or high light) and to biotic stress (pathogens) does occur. A common feature in the response to all stresses is the onset of oxidative stress, through the production of reactive oxygen species (ROS). As hydrogen peroxide and superoxide are involved in stress signaling, a tight control in ROS homeostasis requires a delicate balance of systems involved in their generation and degradation. If the plant lacks the capacity to generate scavenging potential, this can ultimately lead to death. In grapevine, antioxidant homeostasis can be considered at whole plant levels and during the development cycle. The most striking example lies in berries and their derivatives, such as wine, with nutraceutical properties associated with their antioxidant capacity. Antioxidant homeostasis is tightly regulated in leaves, assuring a positive balance between photosynthesis and respiration, explaining the tolerance of many grapevine varieties to extreme environments. In this review we will focus on antioxidant metabolites, antioxidant enzymes, transcriptional regulation and cross-talk with hormones prompted by abiotic stress conditions. We will also discuss three situations that require specific homeostasis balance: biotic stress, the oxidative burst in berries at veraison and in vitro systems. The genetic plasticity of the antioxidant homeostasis response put in evidence by the different levels of tolerance to stress presented by grapevine varieties will be addressed. The gathered information is relevant to foster varietal adaptation to impending climate changes, to assist breeders in choosing the more adapted varieties and suitable viticulture practices.
